Detailed description of the invention
Now simultaneously referring to Fig. 1 to Fig. 3, the bail 100 according to one embodiment of the invention is shown.Bail 100 is lenticular wire section, and it is used as the anchor in brushing tool (particularly toothbrush), to be fixed on by U-shaped brushing cluster in bunch hole that formed in the head of the jug apparatus of such as toothbrush.Bail 100 has substantial rectangular cross section (longitudinal section and cross section) and axis A-A is microscler along the longitudinal.Certainly, other shape can be utilized to form this bail.
This bail 100 is by the periphery definition comprising top edge 10, feather edge 11, first side edge 12 and second side edge 13.This bail 100 has length L, height H and thickness t.The length L of bail 100 will depend on its bunch hole size that will insert, but for bunch hole of 1.7mm, preferable range is 2.09 to 2.13 millimeters, and is most preferably about 2.11 millimeters.Bail 100 height H also depends on the size of its final use, but for bunch hole of 1.70mm, preferable range is 1.49 to 1.51 millimeters, and is most preferably about 1.50 millimeters.Equally, bail 100 thickness t also will depend on its final use, but preferable range is 0.24 to 0.26 millimeter, and be most preferably about 0.25 millimeter.But the present invention not so limits in all embodiments and can utilize other size.Definite size in any final products, by the type and size by a bunch hole size, brushing cluster, uses the brushing tool type etc. of this bail to decide.And although bail 100 is illustrated as have overall uniform thickness t, height H and length L, one or more in these sizes can be that reduce gradually and/or irregular.
In the illustrated embodiment, the edge 10-13 of bail 100 is essentially smooth.But in other embodiments, one or more in edge 10-13 are configured as the pressure providing additional cluster maintenance and/or reduce at brushing cluster turn of bilge.For example, lateral edges 12-13 can be jagged, sharp-pointed or band barb, and feather edge 11 can be round.
Bail 100 also comprises the first first type surface 20 and the second first type surface 21.Second first type surface 21 make bail 100 relative to the first first type surface 20 is for flat rectangular platy structure.First first type surface 20 comprises and is formed in the first first type surface 20 and covers first group of groove 30 of whole first first type surface 20 substantially.Institute fluted 30 is arranged to substantially parallel to each other and spaced at equal intervals each other.But in certain embodiments, fluted 30 can not be substantially parallel to each other and distance between adjacent grooves can change brokenly or as the function of one or two distance in lateral edges 12-13.
Due to groove 30 result spaced apart, continual ridge 31 is formed between adjacent grooves 30.Preferably, this ridge 31 is elongate strips and not segmentation.In other words, preferably, the first first type surface 20 does not comprise the groove intersected each other.In brief, the groove pattern on the first first type surface 20 preferably there is no any crossing groove.
For illustrated preferred embodiment, groove 30 has linearity configuration, and each groove 30 extends along recess axis B-B.But in other embodiments, groove 30 can be bending, meander-shaped or irregularly shaped.
Groove 30 preferably with 0.29 to 0.31 millimeter and most preferably about 0.30 millimeter distance D and be spaced apart from each other.Groove 30 preferably has the width W of 0.09 millimeter to 0.11 millimeter, and is most preferably about 0.10 millimeter.In one embodiment, preferably, the ratio between distance D and width W 3.0 to 4.0 scope and be most preferably 3.0.Groove 30 has 0.09 millimeter to 0.11 millimeter and is most preferably the degree of depth of about 0.11 millimeter.But the definite size of groove and its pattern can be different to a great extent and do not think restriction the present invention, unless stated clearly in the claims.But in one embodiment, the degree of depth of groove 30 preferably and be not more than 1/3rd of bail 100 thickness t.Also find that making groove 30 have the degree of depth being greater than thickness t 1/3rd causes the improper distortion of line/bail 100.
Groove 30 extends the whole height H of bail 100, extends to top edge 10 from feather edge 11.Groove 30 is directed to tilt relative to longitudinal axis A-A on the first first type surface 20 of bail 100.Consider in another mode, the recess axis B-B of each in the groove 30 and longitudinal axis A-A of bail 100 forms non-perpendicular angle.More specifically, the recess axis B-B of groove 30 is crossing with longitudinal axis A-A with acute angle theta, and acute angle theta is chosen as especially provides sufficient bunch of maintenance and the structural intergrity keeping bail 100 when being inserted in toothbrush.Also amazing and be surprised to find that acute angle theta realize needed for enhancing bunch maintenance target in play decisive role, also depend on the metal of structure.Also find groove pattern angle allow use more cheap and/or softer metal and can not cause undesired line be out of shape and/or curling.But selected metal should be soft to making the impression of groove pattern cause undesired distortion and curling.For example, find that aluminium is unaccommodated in most cases.In the desirable embodiment of one, select to be used for the metal of bail 100 and make its Brinell hardness be less than the Brinell hardness of nickel-Yin but be greater than the Brinell hardness of aluminium.
By experiment, find the bail 100 in order to make good behaviour from brass, need acute angle theta to be 40 degree to 70 degree, be more preferably 55 degree and 65 degree and most preferably about 60 degree.For brass, when acute angle theta is less than 40 degree, line has the tendency of distortion and coiling.But, for brass, when angle is greater than 70 degree, be difficult to impress angled groove pattern.And, when groove acute angle theta within the required range time, when the experiment using the destructive testing of toothbrush to carry out shows compared with being with groove or the anchor not with groove with other, bunch maintenance increases surprisingly up to 25%.
Groove 30 is orientated and is inclined upwardly to top edge 10 from feather edge 11 to second side edge 13 from first side edge 12 on the first first type surface 20.Certainly, if desired, groove 30 can be arranged in the opposite direction, that is, be inclined upwardly to top edge 10 to first side edge 12 from feather edge 11 from second side edge 13.Second first type surface 21 of bail 100 is preferably the smooth surface of essentially no groove or other pattern.In other embodiments (as by hereinafter about Fig. 7 to Fig. 9 discuss), the second first type surface 21 also can be patterned as band groove.
Mould roll extrusion or punching press latten(-tin) can be utilized to form groove 30 and then this sheet to be cut into required band, then the cutting of this band is formed bail 100.
Now simultaneously referring to Fig. 4 to Fig. 6, toothbrush 200 will be described, each wherein in brushing cluster 50 is anchored in bunch hole 215 by one of bail 100.Although show brushing cluster 50, also can use other cleaning element, comprise elastomeric fingers, fiber etc.Toothbrush 200 comprises head 210 and extends to the neck 220 of microscler handle.Multiple bunches of holes 215 are formed in the front surface 211 of head 210.Head 210 is made up of such as polyacrylic duroplasts usually.
Each front surface 211 from head 210 in multiple bunches of holes 215 in toothbrush head 210 is along central axis C-C to downward-extension.Bunch hole 215 is preferably the circular inner hole be formed in head 210.Certainly, if desired, bunch hole 215 can be formed as other shape.
During manufacture, brushing cluster 50 bends to U-shaped and is fixed in bunch hole 215 by bail 100.Bail 100 is driven in bunch hole 215 and makes each brushing cluster 50 bend to U-shaped and comprise turn of bilge 51 and two extension legs 52,53.The leg 52,53 of brushing cluster 50 upwards extends and from hole 215 out and above the front surface 211 of head 210.The turn of bilge of brushing cluster 50 or sweep 51 contact the feather edge 11 of bail 100, and two legs 52,53 upwards extend and limit the visible bristle of toothbrush.
See that two lateral edges 12-13 of each bail 100 extend in the opposing sidewalls in each hole 215 slightly.The gyrobearing comprising the plane of each bail 100 is not vital, that is, bail 100 is by making it before the mounting differently to rotate around the gyrobearing of its central vertical axis from about 45 degree, installs to take any required orientation.But preferably, bail 100 is positioned to make in this bunch of hole 215 the longitudinal axis A-A of bail 100 to be substantially perpendicular to the central axis C-C in bunch hole 215.
Now simultaneously referring to Fig. 7 to Fig. 9, bail 100A is according to a second embodiment of the present invention shown.The basic structure of bail 100A is identical with the basic structure of bail 100.Therefore, suffix " A " identifies corresponding component and feature to use identical Reference numeral to add.In order to avoid redundancy, being applicatory by understanding aforementioned discussion, those features of the bail 100A different from bail 100 will being only discussed hereinafter.
Be that, except first group of groove 30A except being formed in the first first type surface 20A, the second first type surface 21A of bail 100A comprises second group of groove 40A in the main difference between bail 100A and bail 100.Discussion above about the groove 30 of bail 100 is also applicable to groove 30A and groove 40A substantially and is combined in by reference herein.But it should be noted that in this embodiment of the invention, bail 100A is not limited to the exact range of acute angle theta.But still preferably acute angle is 40 degree to 70 degree.
It should be pointed out that the groove 30A be formed in the first surface 20A of bail 100A is orientated to be inclined upwardly to top edge 11A to second side edge 13A from feather edge 10A from first side edge 12A.But the groove 40A be formed in the second surface 21A of bail 100A is oriented on the second first type surface 21A to be inclined upwardly to top edge 10A to first side edge 12A from feather edge 11A from second side edge 13A.In other words, groove 30A and groove 40A extends on reverse inclination direction.Certainly, groove 30A and groove 40A well azimuth can be alternately.Preferably, groove 30A and groove 40A be arranged so that its along top edge 10A and feather edge 11A opening along bail 100A length alternately.
